What are the header size variables?

I am wondering what is the header size capabilities in pixels?

There is no limit to how tall the actual header can be.  However, images that are placed inside of a header have a pixel limit of 300-pixels tall.  The width of the header is limited by the max width of a form (since they are the same width), and the maximum width that a form can be is 1500 pixels wide.
As for the minimum height and width, those are defined more by the margins and the font sizes you choose (if you choose text).  For width, forms have a minimum width limitation of 300 pixels wide.  For the height, the effectual minimum height is 50 pixels tall, but an image or a font larger than the minimum would increase that minimum.
I'm curious to know if you have needs beyond those limitations and what the use case is.  Do you need to insert an image in the header to be greater than 300 pixels tall?

  • Why we use variables what  are the advantages of variables

    hi
      can u tell me why we use variables and where we use variables
    ashwin

    hi Ashwin!
    Variable are used for providing the parameters for a query at real time.  that means we can dynamicall specify some what exalty the query should display in the query  for example we can use a variable on the charectersitic like country so that we can decide the contents of the query to will be relavent to the countries we specified.
      Advantages of using the varibles in a query are
       1) we can build a single query which can be used by all. Ex:we can generate a report for all the customers seperatly by using a single query and just by changing the value in the variable at runtime
      2) if we use the processing type authorization for a variable. We can limit the user from accessing the information which he is not authorised to see in the report. This will also make us personalize the query based on the user who is accessing the report.
    Sap help on overview and usage and the types are given in the following link:

  • What's the maximum size a varchar2  variable can hold for and NDS Stmnt?

    What's the maximum size a varchar2 variable can hold for and NDS Statement? I read that NDS is good for doing EXECUTE IMMEDIATE on statements that aren't too big. The 10g PL/SQL manual recommends using DBMS_SQL for statements that are too large, but it never gave a limit for what too large was. Does anyone know offhand?

    The limit is the same as the length of varchar2 variable within PL/SQL - that is varchar2(32767).It's not documented, but intermediate concatenation result can hold up to (64k-1) :
    Connected to:
    Oracle9i Enterprise Edition Release 9.2.0.8.0 - Production
    declare
      part1 varchar2(32767) := rpad('begin null;', 32767);
      part2 varchar2(32767) := lpad('end;',        32767);

  • What are the best practices to use GLOBAL Variables

    Hi,
    Please guide how Global Variables can be declared and how they can be initialized.
    Further please guide what are the impacts of Global Variables(if any) on the memory of CLIENT or SERVER, if they are not initialized or freed up after usage.
    Thanks.
    Regards.

    My preference is not to use them and to use parameters or package variables. There is not real control on globals so you can end up with an applicatios that has lots of them that are only used once but persist for the user session.I second that. I don't know how often I searched for bugs caused by typos in the names of global variables. Plus the fact that they are only of datatype VARCHAR2. If you are using share_library_data you could also use Package globals in a forms library to share data between called and calling forms. Or you could use a database package...

    What is the best way to create the correct space for baseball jersey names and numbers? along with making sure they are the right size for large printing.

    Buying more hard drive space is a very valid option, here.  Editing takes up lots of room, you should never discount the idea of adding more when you need it.
    Another possibility is exporting to MXF OP1a using the AVC-I codec.  It's not lossless, but it is Master quality.  Plus the file size is a LOT smaller, so it may suit your needs.

  • What are the basic difference in the putting a variable in Query

    what are the basic difference in the putting a variable in
    1. Characteristic Restrictions Vs 2. Default Values

    Example - Cost Center Analysis Report - If I have Controlling Area in
    Char Restricitons Only - I have restricted it to say ABC Controlling Area or a Variable- Report will be hardcoded to ABC Controlling Area or the Input Value entered during Runtime - After Execution, The Same cannot be changed in the report.
    Assuming I will not have Controlling Area in the report means not in Rows n Columns.
    You might have seen no change - > Did you place material in Rows or Columns ?

  • What are the differences between attributes and variables?

    I am trying to develop a firmer understanding of the difference between attributes and variables. I understand attributes are lexically scoped to a class and variables are lexically scoped to the enclosing block. The lifetime of an attribute is linked to a class' instance. What is the lifetime of a variable? What is the lifetime of variables declared in a script file's top-level?

    It depend on whether the script is running in standalone mode or been called by others (library mode).
    If running as standalone, the variable of the script in the top level exists until the the script exit. If run as library mode, the variable in the top level of the script will never get to execute. Only the function and class available for call.
    Try calling another script with top level variable (place print statement to verify), you realize in library mode, it will never been called. That's why the main method as in Java is never needed because of this reason.

  • Looking for new laptop what are the differences between pro and air? Besides size. Does the air preform like the pro?

    Looking for new laptop what are the differences between pro and air? Besides size. Does the air preform like the pro?

    The NEW macbook Pro and Air are EXTREMELY close in form factor
    The newest macbook Pro is essentially a larger macbook Air with Retina display and options for speed in increasing prices up to an independent graphics and quad core processor.
    both Air and new Pro now have PCIe SSD and permanent RAM.
    The Air is the lightweight portable form factor, fast to boot and shut down, but with longer battery life than any of the macbook pro in 13"
    Now the new macbook Pro and macbook Air are extremely close in form factor and nature.
    both have 802ac wifi
    both have permanent RAM, no superdrive
    both are slim profiles and SSD
    The only real differences now are (in the most expensive Pros) faster processors and quadcore processors and top end model autonomous graphics.
    ....and of course the retina display
    both are now "very good for travel"
    Other than features the form factor of the Air and Pro are VERY close now,....so now its merely a matter of features and price more than anything.
    You need an external HD regardless of what you get for backups etc.   Drop into an Apple store and handle both and make your choice based on features, such as Retina or non-retina, .... both at a distance now look like the same computer.
    The Pro weighs more, ....but nowhere near what it used to just a month ago on the older macbook Pros
    The NEW macbook Pro is a different creature entirely than the older macbook Pro, .....the new Pro is thicker than the Air, but id frankly call the NEWEST Pro a "macbook Air with Retina display" , or
    Maybe a “macbook Air PRO with Retina display” 
    Instead of Air VS Pro now,.....its really a smooth transition from Air to pro without comparing say, 2 different creatures, now its like contrasting a horse from a race horse.
    Either one in 8gig of RAM (preferably)... the 4gig upgrade costs very little,  the I7 you will notice only 15% faster on heavy applications over the I5, and NOTHING on most APPS.....I5 has longer battery life.
    As you see below, the non-Retina 13" AIR is 82% of the Macbook with Retina display in resolution
    there is no magical number of pixels per inch that automatically equates to Retina quality.
    http://www.cultofmac.com/168509/why-you-might-be-disappointed-by-the-resolution- of-those-new-retina-display-macs-feature/
    A huge internal SSD isnt a game changer for anything, you need an external HD anyway
    what you WONT READ on Apple.com etc. is that the larger SSD  are MUCH FASTER due to SSD density

    We will customize a very detailed reply, but
    (a) What are the properties of your source media?
    (b) What did you or the program set as the project preset to match the properties of the source media?
    (c) What specific requirements do you have for this H.264.mov export file?
    File size can be a compromise between bitrate, file size, and quality.

  • What are the objects that support variables?

    What are the objects that support variables?

    Using Variables: The Variable Wizard and the Variable Editor
    Definition
    Variables are parameters of a query that you defined in the Query Designer and that are filled with values when you execute the query or Web application. They serve as a store for characteristic values, hierarchies, hierarchy nodes, texts and formula elements, and can be processed in different ways.
    The processing type determines how a variable is filled with a value for the runtime of the query or Web application.
    There are different types of variables depending on the object for which you want to define variables. These types specify where you can use the variables.
    Variables are reusable objects. This means that when you define a variable for a query in the Query Designer, this variable can be used in all other queries. Variables are not dependent on the InfoProvider, only on the InfoObject. A variable that you define for an InfoObject is available in all InfoProviders that use this InfoObject.
    Use
    Variables enable you to customize queries flexibly (parameterize the query) possible. If you use variables in the Query Designer, do not select any fixed characteristic values, hierarchies, hierarchy nodes, texts, or formula elements. Instead, set up variables as place holders. These are then filled with values when the query is running (when you insert the query into a workbook, when you refresh the workbook or when you execute the query on the Web. You can use one query definition as the foundation for many different queries if you use variables.
    You want to create one query for all the people responsible for customer groups, who each only evaluate the data for one customer group. In the Query Designer, you insert a variable for the characteristic u2018customer groupu2019. Just before the query is executed, decide for which customer group(s) you want the query to apply to.
    There are two tools in the Query Designer for designing and changing variables.
    The variable wizard takes you step-by-step through the process of defining a variable. Each individual step is context-sensitive and is adjusted according to the combination of variable and processing types used. This means that the variable wizard only offers the selection options that are permitted for that combination of variable and processing types. For more information, see Defining Variables with the Variable Wizard.
    The variable editor dialog box offers all of the selection options for changing an existing variable. The individual fields in the dialog box show the settings affected in the variable. You can change these settings here. If you want to make the changes using a step-by-step process with explanatory texts, you can jump to the variable wizard using . For more information, see Changing Variables in the Variable Editor.
    Integration
    The variable wizard and the variable editor are functions in the Query Designer and are context-sensitive.
    In principle, the two dialog boxes appear wherever you can enter constants (that is, values) in input fields. One of these input fields is the Entry of Variables checkbox.  If you select this option, the following options for using a variable appear, instead of a fixed value:
    ·        The variables that are available appear in the dropdown box for the input field. You can select a variable from the dropdown box.
    ·        The symbol  Change Variable appears next to the Entry of Variables checkbox. You can change the variable using  . The Variable Editor dialog box appears.
    ·        The symbol  New Variable appears next to the Entry of Variables checkbox. Choose  if you want to create a new variable. The Variable Wizard dialog box appears.
    By way of an example, when defining conditions for the value limit of the condition, you can not only enter fixed values but also formula variables. Mark the Entry of Variables checkbox and you can then use the options described above. The settings are context-sensitive so that the formula variables that only those formula variables that are available appear in the dropdown box.  The variable wizard is set up automatically in the same way for entering formula variables.
    You can also get to the variable wizard and the variable editor from the context menu of those objects for whose values you can define variable placeholders. From the context menu, choose New Variable. The SAP BW Variables Wizard appears. In the context menu for variables that have already been defined, you can choose Edit. The SAP BW Variables Editor appears.
    In the InfoProvider objects dialog box, you select a characteristic (for example, Order) and from the context menu, choose New Variable. You reach the variable wizard, which is already set up for you to enter a characteristic value variable.
    In the InfoProvider objects dialog box, you select a characteristic value variable and from the context menu, choose Edit. You reach the variable editor where you see all of the settings for the variable. You can make changes to the variables here.
    Variable Types
    Definition
    The type of variable being used. This determines the object that the variable represents as a placeholder for a concrete value.
    Structure
    There are different types of variables depending on the object for which you want to define variables. These types specify where you can use the variables.
    ·        Characteristic Value Variables
    Characteristic value variables represent characteristic values and can be used wherever characteristic values are used.
    If you restrict characteristics to specific characteristic values, you can also use characteristic value variables. See, Restricting Characteristics.
    ·        Hierarchy Variables
    Hierarchy variables represent hierarchies and can be used wherever hierarchies can be selected.
    If you restrict characteristics to specific hierarchies or select presentation hierarchies, you can also use hierarchy variables. See Selecting Hierarchies
    ·        Hierarchy Node Variables
    Hierarchy node variables represent a node in a hierarchy and can be used wherever hierarchy nodes are used.
    If you restrict characteristics to specific hierarchy nodes, you can also use hierarchy node variables. See Restricting Characteristics: Hierarchies
    ·        Text Variables
    Text variables represent a text and can be used in descriptions of queries, calculated key figures and structural components.
    You can use text variables in the description of calculated key figures, restricted key figures, selections and formulas when you create them. See Defining Calculated Key Figures, Defining Restricted Key Figures, Defining Selections, and Defining Formulas.
    You can change the descriptions in the properties dialog box. See Query Properties Calculated Key Figure Properties Restricted Key Figure Properties, and Selection/Formula Properties.
    ·        Formula Variables
    Formula variables represent numerical values and can be used in formulas. See Defining Formulas.
    In addition, numerical values are used for selecting exceptions and conditions and you can also use formula variables here. See Defining Exceptions and Defining Conditions
    You can use a formula variable for the interest rate in order to process the current interest rate, after you have executed the query or Web application.

  • What are the various system variabels in ABAP

    What are the various system variabels in ABAP?

    u can view all the system variables in SYST TABLE Also   ...............
    ABAP System Fields
    ABAP system fields are always available in ABAP programs. The runtime system fills them according to context. They can then be used in programs to query the system status. System fields are variables but you should always treat them as though they were constants, and only read them. If you change their values, important information for the flow of the program may be lost. In exceptional circumstances, system fields may be overwritten in an ABAP program to control the system – for example, SY-LSIND (for navigating to a detail list).
    With one exception the names and data types of the system fields are stored in the ABAP Dictionary in the SYST structure and realized as components of the predefined structure SY in ABAP programs.
    The system field SY-REPID is not part of SYST or SY. Instead, every program contains the predefined constants SY-REPID and SYST-REPID, which both contain the name of the corresponding program. Furthermore, there are two predefined types of the same name, SY-REPID and SYST-REPID.
    All system fields are addressed using SY field name and their types using SYST field name.
                                                                                    Alphabetical Overview
    The following table lists the definitions of the structure SYST in the ABAP Dictionary alphabetically. The character in the first column indicates how you can use the corresponding system field in ABAP programs. Name is the name of the component, Type is the Dictionary data type, and Length is the field length defined in the Dictionary. The Use column shows in which environment the system fields are set. The Description indicates the content.

    For database accesses with Open SQL, SY-MANDT is used as the first key field of the WHERE clause.
    SY-MODNO
    Indexes external modes. Zero in first mode. In new modes, opened using the Create Mode function or by calling a transaction using /o, it is raised by 1. If previous modes were deleted, the free numbers are used first. Modes opened using  CALL TRANSACTION … STARTING NEW TASK start back at 0.
    SY-UNAME
    Logon name of user, for example KELLERH, BC400-01.
    Date and Time Information
    The following system fields are always set automatically. If necessary, the GET TIME statement synchronizes the application server time with that of the database server and writes it to the system field SY-UZEIT. SY-DATUM and the system fields for the local time zone, that is SY-TIMLO, SY-DATLO, and SY-ZONLO are also reset.
    SY-DATLO
    Local date of user, for example 19981129, 19990628.
    SY-DATUM
    Current (application server) date, for example 19981130, 19990627.
    SY-DAYST
    During daylight saving time X, otherwise empty.
    SY-FDAYW

    SY-ZONLO
    Time zone of user, for example CET, UTC.
    Information on the Current ABAP Program
    SY-CALLD
    SY-CALLD contains SPACE if the program is the first and only program in a call chain. SY_CALLD contains 'X' if the program is a called program in a call chain (see ABAP Calls Overview).
    ·        SY-CALLD is set to ‘X‘ in a program called using CALL TRANSACTION, CALL DIALOG, or SUBMIT … AND RETURN.
    ·        SY-CALLD is set to SPACE in a program called using LEAVE TO TRANSACTION, entering a transaction code on a screen, and processing batch input folders. 
    ·        With SUBMIT (without RETURN) SY-CALLD retains the previous value.
    SY-CPROG
    In externally called procedures, the name of the calling program, otherwise the name of the current program. If an externally called procedure calls another external procedure, SY-CPROG keeps the name of the first main program and is not given the name of the main program of the further caller.
    SY-DBNAM
    With executable programs this is the linked logical database.
    SY-DYNGR
    Screen group of current screen. You can assign several screens to a common screen group. You can use this, for example, to modify all of the screens in the group in a uniform way.
    SY-DYNNR
    Number of current screen During the selection screen processing, SY-DYNNR contains the screen number of the current selection screen. During list processing, SY-DYNNR contains the number of the container screen. While a subscreen is being processed, SY-DYNNR contains its screen number. This also applies to tabstrips.
    SY-LDBPG
    With executable programs, the database program of the linked logical database.
    SY-REPID
    Name of current ABAP program. With externally called procedures this is the name of the procedure’s main program.
    If SY-REPID was transferred to an external procedure as an actual parameter before Release 6.10, the formal parameter was not given the name of the caller, but the name of the procedure’s main program. SY-REID had to be transferred to an auxiliary variable before the call or you had to use SY-PROG.
    As of Release 6.10, SY-REPID is a separate constant that is no longer part of the structure SYST or SY. It can be transferred to external procedures directly.
    SY-TCODE
    Name of current transaction code.
    Background Processing
    SY-BATCH
    SY-BATCH is set to X in an ABAP program running in the background. Otherwise it is empty.
    Batch Input
    SY-BINPT
    SY-BINPT is set to X during processing of batch input folders and in ABAP programs called with CALL TRANSACTION USING. Otherwise it is empty.
    ·         OPTIONS FROM in the CALL TRANSACTION USING statement can set SY-BINPT to empty for the whole program execution, as well as at the end of the BDC data.
    ·         In CATT procedures, SY-BINPT is always empty.
                                                                                    ABAP Programming
    Constants
    SY-ABCDE
    Contains the Alphabet. Can be used to access individual letters independently of the codepage by specifying offset.
    SY-ULINE
    Contains a horizontal line with length 255. Can be used when creating the list.
    SY-VLINE
    Contains a vertical line (|). Can be used when creating the list
    Loops
    SY-INDEX
    SY-INDEX contains the number of loop passes in DO and WHILE loops, including the current loop pass.
    Character Strings
    SY-FDPOS
    Found location for operations with character-type fields.
    ·        If the operators CO, CN, CA, NA, CS, NS, CP, NP are used in comparisons, SY-FDPOS is assigned offset values depending on the comparison result.
    ·        SEARCH … FOR … sets SY-FDPOS to the offset of the found search string.
    Internal Tables
    SY-TABIX
    Current line in an internal table. With the following statements SY-TABIX is set for index tables. With hashed tables, SY-TABIX is not filled or it is set to 0.
    ·        APPEND sets SY-TABIX to the index of the last table row, that is the total number of entries in the target table.
    ·        COLLECT sets SY-TABIX to the index of the existing or appended table row. With hashed tables, SY-TABIX is set to 0.
    ·        LOOP AT sets SY-TABIX to the index of the current table row at the beginning of every loop pass. After leaving a loop, SY-TABIX is set to the value it had before entering the loop. With hashed tables, SY-TABIX is set to 0.
    ·        READ TABLE sets SY-TABIX to the index of the table row read. If no row is found with binary search while reading, SY-TABIX contains the index of the next-highest row or the total number of rows +1. If no row is found with linear search while reading, SY-TABIX is undefined.
    ·        SEARCH  0). Each time an interactive list event occurs, the system automatically increases SY-LSIND by 1. SY-LSIND can be changed in the ABAP program to navigate between detail lists. Changes to SY-LSIND are not taken into account until the end of the list event. Therefore, any manipulation of SY-LISND should be done using the last command of the processing block.
    SY-LSTAT
    ID for list levels within the program. SY-LSTAT can be filled with values during list creation in the ABAP program. The value valid when the list is completed is saved with the list. In the case of an interactive list event, SY-LSTAT is set to the value it was assigned during the creation of the list from which the event takes place. SY-LSTAT is no longer maintained and should therefore no longer be used.
    SY-STACO
    Number of the first displayed column of the list from which the event was triggered. Counting starts at 1.
    SY-STARO
    Number of the upper-most displayed row of the upper-most page of the list, from which the event was triggered. Counting begins at 1. This does not include the page header.
    Printing Lists
    When printing lists, the spool and runtime systems require certain internal information, which is available in the following system fields and is set during print activation.
    SY-CALLR
    Contains a value that displays where printing was started, for example NEW-PAGE for program-controlled printing or RSDBRUNT for printing from the selection screen.
    SY-PRDSN
    Contains the name of the spool file during printing.
    SY-SPONO
    Contains the name of the spool number during printing.
    SY-MAROW, SY-MACOL
    The SET MARGIN statement fills the system fields SY-MAROW and SY-MACOL, which determine the number of lines on the upper margin and the number of columns on the left margin when printing.
    Print Parameters
    The print parameters are transferred to the spool system by the runtime system in a structure of dictionary type PRI_PARAMS. Before this structure was used, its purpose was served by system fields. Today a subset of the PRI_PARAMS structure is still written to system fields with the same names when printing is activated. This information is redundant and should not be used.
    Messages
    If you execute the MESSAGE statement, the following system fields are set. If you execute the MESSAGE … RAISING statement in function modules and methods, these fields are also set in the calling program, if it handles the exception.
    SY-MSGID
    SY-MSGID contains the message ID.
    SY-MSGNO
    SY-MSGNO contains the message number.
    SY-MSGTY
    SY-MSGTY contains the message type.
    SY-MSGV1,…,SY-MSGV4
    SY-MSGV1 to SY-MSGV4 contain the field contents that are used for the message’s placeholders.
